2 Claims.

This invention relates to mops, and has been illustrated as embodied in a mop'having a twisted wire frame, though in many of its vaspectsV it may be used with quite different types of mops. `The form of the mop chosen for illustration includes atwisted wire frame with brous twisted strands secured between the twisted wires comprising the frame and With the ends of the frame brought ltogether and welded to form a loop. It also includes a handle bracket stamped from a metal sheet and'V secured pivotally around the twisted wire frame, at the point of the weld. Around the bottom of this handle'member may be secured a cushion member of rubber or the like to protect the surface handleV socket chosen for being polished. The illustration is of the coil spring wire type, and is secured on the handle bracket.

Among the objects of this invention are the provision of a more sturdy tofore been known, and the frame than has hereprovision of a more convenient economical and reliable means of attaching the handle to the mop than has heretofore been available.

With these and various the invention may consist tures of construction and other objects in view, of certain novel feaoperation, as will be more fully described and particularly pointed out in the speciiication, dr pended hereto.

Pivotally secured around the joint in the frame is a handle bracket 2li which comprises one of the major features of this invention. This brack- 10 et 20 may be made from one piece by stamping and doubling over. In its inished form it comprises a hinged portion Y22 from which extend two similarly shaped sides. These sides together make up the shank portion 24 andthe 15 clamp portion which comprises'the jaws 26. The jaws are shaped'to form a cylinder which will iit snugly about the frame I0 to reinforce the walls of the jaws and the end of the shank, and may be provided with suitable ribs 28. Located between two of the ribs and close to the jaws are suitable holes through which is passed a tightening bolt 30 which may be screwed into the nut 32. The nut 32 preferably coacts with one or both of the ribs 28 to prevent its turning.

On one side member of the shank member 24 are pressed out threads 34. Screwed onto these threads is a twisted spring wire handle socket member 36 into which may be fastened a handle 38 by any means desired. Of course the threads 34 may be pressed out on both sides of the shank if desired, but itis preferred that they be on one side only, since this is sufcient for the purpose and since their use on both sides would result in occasional difficulty in screwing the handle socket into place, since the threads would not always line up exactly.

It is preferred that the bolt 30 be tightened up sufficiently to make the jaws just tight enough to hold the mop and handle in any desired position with respect to the mop, while at the same time being sufliciently loose to permit a ready change in this relative position.

Although the strands of the mop will ordinarily keep the handle bracket 2D well above the floor, special padding may be provided in order to further guard against marring the -surface that is being polished. Although this padding may take many forms, two of the most satisfactory are those shown at 40 in Figure 4 and at 42 in Figure 5. In each case it is seen that the padding is wrapped completely around the jaws of the bracket. This padding may be made of sheepskin, rubber or any other suitable material. According to the fbrm shown in Figures 2 and 4, the pad- 55 ding may be secured in place by the bolt 30 and nut 32. This form of attachment, however, has the disadvantage that it leaves the bolt projecting undesirably far unless special shaping of the parts is relied on to prevent this. The form of padding shown in Figure 5 is therefore somewhat preferable. In this form the padding is secured in place by a pair of rivets 44. Bolts may also be used in the same positions, inasmuch as such bolts may be quite short since they do not extend through any part of the bracket 20. If desired, a hole may be provided in the padding in line with the bolt 3E' to permit adjustment after the padding has been secured in place.

Although the ribs 28 have been spoken of chiefly as reinforcing ribs, the center of these three ribs is provided primarily for another purpose. In commercial production there will occasionally be projecting bits of metal at the point of the weld, but any diiculty due to the presence of these burrs is avoided by providing these outwardly embossed ribs at this point. To keep the bracket centered so that the rib will lie over the burr, the strands are crowded close up to the desired position of the bracket, locking it against lateral movement.

It is to be understood that many other embodiments of the invention, including some in improved form, will be apparent, and in the course of time more will be devised by those skilled in the art. It is not desired that this invention be limited to the details described, for its scope includes all such forms or improvements as come within the spirit of the following claims construed as broadly as the prior art will permit.

What is claimed is: 1

1. The combination of a mop having a long straight frame portion generally round in cross section, a handle bracket comprising gripping means fitting along a Central portion of and partially around and in contact with said frame portion and lightly clamping the same to permit a resisted pivotal movement, said frame having a weld at its center and said gripping means having an internal annular groove positioned around said weld to loosely receive any burr on said Weld.

2. A mop handle structure adapted to engage a straight portion of a twisted wire frame including: a coiled spring wire handle socket member; connecting means for connecting said socket member and said frame consisting solely in a pair of clamp jaws adapted to lie in contactual engagement with said straight frame portion, and each having integral therewith a shank, and screw adjustment means extending through said Shanks adjacent to said clamp jaws and adjusting the pressure of said clamp jaws on the frame member independently of any other adjustments; the upper portion of said shanks extending into said socket member and engaging each other at longitudinally spaced points to form therein a substantially non-varying plug member, and being suiciently large to be tight tting in said socket; and the lower parts of said Shanks and the clamp jaws being spaced apart and being free from obstruction other than the mop frame to permit their free adjustment by said screw means, and the shanks being so shaped that the jaws and lower parts of the shanks are resiliently urged to such spaced-apart position so that releasing the screw means causes them to release their tension on the frame.
